Fees, valuation & enforcement
Permit fees are a project input. Enforcement exposure is a project risk. Use the official schedule where available, then confirm valuation, trade permits, plan review, and inspection charges with the Authority Having Jurisdiction.
Official fee pathway
The final charge may depend on declared construction value, occupancy classification, square footage, plan review, state surcharges, trade permits, technology fees, and inspection activity. Do not use a neighboring city’s fee table as a substitute for this jurisdiction.

Ask the counter to confirm current charges before submitting a project with multiple trades or a change of use.
Financial exposure
Plan for building, mechanical, plumbing, electrical, fire, energy, zoning, septic, right-of-way, or other reviews that the project scope triggers. The lowest initial permit fee is not always the lowest project cost.
Enforcement exposure
When work begins without authorization, the agency may halt the site, require corrective plans, impose additional fees, withhold inspection release, or require concealed work to be exposed for review.
Closeout exposure
A missing final inspection or certificate can complicate occupancy, refinancing, sale, insurance, and utility connection. Preserve the approved plans and signed inspection record through closeout.
Professional field note
Even when a cosmetic or minor project does not require a building permit, zoning, floodplain, shoreline, historic, utility, fire, or right-of-way controls may still apply. Confirm the full jurisdictional picture before work starts.

This record is marked Municipal Fallback. Confirm whether a city, state agency, or other local authority controls the parcel before filing.

N/A for ordinary building permits; a 2024 county solar-facility ordinance requires complete solar site-plan review within 45 days, but that timeline does not apply generally to building permits.
Call 843-355-9321 (ext. 5300 or inspector ext. 5303) with the address, tax map or permit number, inspection type, contractor name and contact phone. Williamsburg County requires at least 48 hours' notice and cannot guarantee a specific time, only before or after lunch. Approved plans must remain on site and the permit must be posted. Residential sequence includes foundation, slab, piers/CMU where applicable, wall/roof sheathing, rough-in, framing, insulation, temporary power and final inspection.
Williamsburg County's 2022-08 amended building/fire-code ordinance and plan guidance require the current South Carolina code cycle. For 2026 this is the 2021 International Building, Residential, Fire, Plumbing, Mechanical and Fuel Gas Codes with South Carolina modifications, the 2020 National Electrical Code, the applicable energy code and ICC A117.1 accessibility standard. N/A; the reviewed current county permit pages do not publish a consolidated minor/cosmetic exemption list. Farm structures may use the South Carolina farm-structure affidavit process, while the county requires applicants to confirm other exemptions with Code Enforcement before work begins.
Why permit costs vary
Building departments commonly calculate charges from valuation, occupancy, floor area, project type, plan review effort, trade scope, state surcharges, and inspection activity. A remodel that appears small on paper may still trigger structural, energy, fire, or utility review. Ask the permit counter which disciplines apply before you finalize the construction budget.
The same discipline applies to enforcement. Correcting unpermitted work after finishes are installed can require demolition, revised plans, additional inspections, and schedule disruption. Authorization is usually the less expensive project-management decision.
